The Ajna Chakra, or third eye, is linked to the pineal gland. Ajna is the chakra of time and awareness and of light. The pineal gland is a light sensitive gland, that produces the hormone melatonin, which regulates the instincts of going to sleep and awakening. It also produces trace amounts of the psychedelic chemical dimethyltryptamine.
While the physiological function of the pineal gland has been unknown until recent times, mystical traditions and esoteric schools have long known this area in the middle of the brain to be the connecting link between the physical and spiritual worlds. Considered the most powerful and highest source of ethereal energy available to humans, the pineal gland has always been important in initiating supernatural powers. Development of psychic talents has been closely associated with this organ of higher vision.
